Group 62 POS CORRECTION
Settings for position correction functions (homing, presets, and cyclic corrections).
With these functions, the user can define the relationship between the actual
position of the drive positioning system and the driven machinery.
Some of the correction functions need an external probe or limit switch to be
connected to the digital inputs of the drive control board or encoder interface
module.
See also section Position correction on page 56.
Note: Only one position correction function can be active at a time. Homing has the
highest priority, cyclic correction the lowest.

62 POS CORRECTION
Firmware block:
HOMING
(62)
This block
• selects homing mode (1…35)
• selects the homing start function
(NORMAL/PULSE) and the source
for the homing start command
• selects the source for the home
switch signal
• selects the sources for the negative
and positive limit switch signals
• defines two homing speed
reference values
• defines the home position
• shows measured position and
calculated cyclic position error for
the cyclic correction function (see
the block CYCLIC CORRECTION
on page 199).
